Energy Efficient Water Heating
Colmac WaterHeat, a division of Colmac Industries, is a world innovator in the production of heat pump water heaters. Utilizing the vapor-compression refrigeration cycle to extract heat from the surrounding air or water, the Colmac WaterHeat heat pump water heater is an energy efficient means of heating water to temperatures as high as 160°F (71°C) in a single pass!

Lowest Energy Cost
This principle of moving heat with a heat pump, rather than generating it by burning fossil fuels or electric resistance, gives water heating heat pumps a higher COP (Coefficient of Performance) than traditional methods of heating water such as boilers or electrical resistance.

Green Energy
Colmac WaterHeat heat pump water heaters are the most efficient method available today for heating water. These extremely high COPs attained with heat pump water heaters make them a green, sustainable energy source requiring no fossil fuels. This can be a central part of a LEED points design and/or qualify for environmental utility incentives or credits where available.

Health/Safety (Sanitary Water)
Safe for potable (sanitary) domestic water systems, the double wall-vented condensers used by Colmac fully isolate the refrigerant from the water system. Additionally, by heating water to 140°-165°F (60°-74°C) in a single pass, Colmac WaterHeat has created a true HACCP (hazard analysis and critical control point) for the eradication of Legionella in hot water storage systems without the use of UV or chemicals.

Reliable Performance
Designed for low maintenance and easy service, the Colmac WaterHeat heat pump water heaters have a life expectancy of 15+ years with some units having a life span of 25+ years. The Colmac WaterHeat single pass system delivers a constant leaving water temperature for continuous water heating whenever the unit is running. All Colmac WaterHeat heat pump water heaters are designed, built and tested in the USA.
